shntool is a command-line utility to view and/or modify WAVE data and properties. It runs in several different operating modes, and supports various lossless audio formats. shntool is comprised of three parts - its core, mode modules, and format modules. This helps to make the code easier to maintain, as well as aid other programmers in developing new functionality. The distribution archive contains a file named 'modules.howto' that describes how to create a new mode or format module, for those so inclined. If you wish to have shntool support shorten, you should install the shorten (also available from SlackBuilds.org) first.
